Specification of Letters Patent No. 230, dated June 14, 183.7.

To all whom it may concern of the city, county, and State of New York,

have invented a new and useful Improve-v., ment in Machinery for Makinga Batting or Web of Fur; and that the following is a full and exactdescription of the construction and manner of operating said machine as?i for supporting and moving the vellum, 'or

invented by me,-that is to say: f Y

Whereas certain machines called carding machines are well known and inuse by vthe :manufacturers of cotton and wool, and other f fibroussubstances and also certain machines 1 placed 'turns in boxes under theplates and Ais are known and used by hatters in conjunction with thecarding machine for making hat bodies of wool, but these machines or.tany combination of them have not heretof` fore been known or used formaking a continued batting, or web of fur; now my ma chine consists inthe application of certain parts of such known machines, in combinavtion with other parts which have not here-l tofore been known or used insaid machines,

the old and ynew parts being so arranged proportioned and combined as toproduce a machine capable of making a batting, or

andk for other purposes; and for the more perfect explanation of my saidmachine reference is made to the drawingshereunto annexed, No. 1 and No.2, where the several parts of my machine are distinguished from eachother by letters of reference.

It commences with a common carding machine, with one main cylinder, withyits usual feed apron, its feed rollers, its licker in. The maincylinder marked, A, has a motion `of about 8O turns in a minute, and itsworkers, and strippers, its fancy, and doiiing cylinder., as representedaround it in dotted lines,

all which is so common and so well known to.

mechanics as to need no `further description,

as it is in no way altered by mm-except bowing in the usual method, andfor other Be 1t known that I, THOMAS BLANCHARD,

purposes, by the following machinery: the

#plates ofthe cardingmachine extendingV backfofvA the card supported infront by two legs and in the rear by being let into and so supported bytwo upright posts marked, 'J

and Lf; Vunder the whole of which, a frame or box is built closeandtight. Two rollers ywire cloth apron, 0;, a, which rollers are markedD E, and are placed in their bearings as representedback of the card;one of Y the rollers on which the driving pulley C is marked D, theother roller which is marked E Ysupports the back section of the vellumy n and turns in boxes attached yto the upright posts and L, above theplates 'o-f the frame, said roller E, and under the plates roller D lay,(having their bearings as before described') horizontal and parallel toeach other, and are at a distance 'of about five feet 5' apart, the backroller E elevated about one foot abo-ve the roller D. Around theserollers `moves like a feed apron said vellum, or wire cloth which isendless; between the upper and lower sides ofthe said vellum and 9 i;

extending nearly to the said rollers D and E is placed a stationary box(shown in section by the red lines b, b, and in perspective at Y) withthe top open to receive the air that comes through Vthe fur and uppersideof the wire vellum; two holes are cut near each other through one ofthe plates of Vthe frame and through the side of the box opening intothe space between the upper, and lower part of the vellum, theseholesbein'g sufiiciently large for the air to pass, which is drawn Vbythe draft of a` fan marked 1F, which 'fan is formed on a horizontalshaft,

having its inner bearing in a 'bo-X between the holes and sustained atthe other end by a post or out rigger; outside of the fan en the shaftis the pulley to drive it marked G. The fan is formed with two heads orflanges about four feet in diameter made fast to the horizontal shaftabout one foot apart; be-

tween said heads are aii'xed four or more fans or buckets, the inner endmade fast to the four sides of the shaft extending-outwards as far asthe outer edge of the heads or flanges and made fast to them; ,throughupright post J and its upper end extending' upward and resting againstthe cams 0f the cam wheel K, the shaded part forming a series ofinclined planes; which gives the motion one way and a spring, M, bearingagainst the end of the journal returns the motion in the oppositedirection from the cam, thus making a reciprocal or vibratory motion,the said cam wheel K is made fast or formed on the inside of the pulleyP; and when this, or the back part of my machine is thus formed,arranged and put together, and then inclosed, a vacuum or exhaustchamber is over the wire vellum into which the fur is thrown by thequick fancy; and then by exhaust-ing said chamber by suction, or draft,the fur is drawn tight upon the vallum, or wire cloth until it passesout with said vellum under roller I'I, which by its vibratory ortremulous motion hardens it into a web of suHicient tenacity to behandled and formed into hat bodies, or used as napping, the motion ofthe machine, is given by the main shaft O, which receives its bearingson the top of the upright posts marked J and L, and on one end of whichis the pulley N, and on the other end the pulley l?, a belt passes fromthe pulley N to the pulley A on the main cylinder shaft, which givesmotion to the carder. A belt on the pulley P to the pulley y gives anincreased motion to shaft e and pulleys S and R. A belt from pulleys Sconveys motion to a small pulley G on fan F. A cross belt from pulley Rconveys a rapid motion to the pulley B on the shaft of the quick fancy,which throws the fur from the doffer into the exhaust chamber; a beltfrom pulley U on the shaft of the doffer conveys mo-t-ion to the pulleyT, which, by a pair of gears conveys a slow motion to the driving roller(number one) of the feed apron; on the opposite end of roller one ispulley Q, which by a belt conveys motion to pulley C on the shaft of theroller D, which gives mot-ion to the vellum apron; a crossed belt onpulley, (number two), conveys motion to pulley X on the shaft of feedingcard; pulley W receives its motion from a pinion wheel on the maincylinder shaft to a large tooth wheelqwhich 0 is made fast to the pulleyW; on an out rig- 5 cards, (except the feed apron) the belts may.

ger, a belt from pulley W gives motion to the doffer over pulley V. Whenall these parts are thus arranged and the body of the machine inclosedtight, including all the be put on the several pulleys as represented;then pass a belt upon the driving pulley of the main shaft from thefirst mover, and all will be in motion. The fur will be received fromthe feeding apron by the feed rollers, and be carried by the licker-into the main cylinder and passing all the workers and strippers it willbe received upon the doffer, and by the quick fancy will be thrown intothe air or exhaust chamber over the wire vellum and by the draft fromthe fan, drawingthe air out through the wire vellum, and by theprogressive motion of the said vellum. The fur. is carried off as abovede.

quantity of fur necessary to feed on the feed apron in a given time, butthe speed and feed must be' governed by the thickness ofv the webrequired and different thicknesses of web required from different kindsof fur to be used for different purposes, consequently the alteration ofthe coperating parts of the machine may be varied according to the skillof the manager.

I do not claim any particular number of revolving fans toV exhaust thechamber of air. Although I have described but one on the one side of thechamber, two or more may be applied or o-ne on each side of the chamberwhen a more powerful draft is required; but it is necessary to regulatethe draft in such a manner that the fur will be deposited equally on allparts of the vellum when a web of a uniform thickness is required, or aweb may be formed thicker on one side than upon the other, or thickestin the center and tapering toward both edges; these variations may beeffected in different ways; a board may be placed in the inside of thebox under the vellum in different positions to break or change thecurrent of air, as it passes through, which will cause the fur todeposit dierently on the vellum; pipes may be placed leading from theinside of the fbox that the air passing into them and out at one end mayregulate the distribution, these pipes may be perforated with holes. Thequick fancy that throws the fur from the doifer will raise suflicientcurrent of air by its rapid motion to carry the fur to the vellum withthe assistance of the draft of the fan.

I do not claim the fan as my invention nor the wire vellum apron, norany part separately, but

I do claim as my improvement or invention- The forming the batting orweb of fur by throwing the fur into a chamber and depositing it on anendless web of Wire cloth, or Vellum revolving around tWo extendedrollers, and by exhausting said chamber of air by a revolving fan on theoutside of said chamber, the air passing through the Wire cloth depositsthe Vfur upon it 'and draws it tight upon the Wire cloth, at the sametime the Wire cloth is forming its progressive motion, and carries thefur under a vibrating roller Which hardensjit to asulioienttenacity tobe handled, and) formed into hat n bodies or used for naps, and thearrangement and combination of the above machinery and partsof'machinery in the manner above described and set forth and for thepurposes aforesaid.
